TPIC6273DW

Overview

The TPIC6273DW is an octal D-type latch manufactured by Texas Instruments, designed for power logic applications. It features eight parallel data inputs and outputs, operating within a supply voltage range of 4.5V to 5.5V. The device utilizes a standard SOIC-20 surface-mount package. Key electrical characteristics include a maximum propagation delay of 27ns at 5V and an output current capability of 8mA. It supports a clock frequency up to 40MHz and functions reliably across an operating temperature range from 0°C to 70°C.

Feature Summary

• Provides octal latching functionality with non-inverting outputs for stable data storage
• Designed for power logic integration with robust output drive capabilities
• Operates on a single-ended input configuration with a master reset function

Applications

• Parallel data storage in digital systems
• Interface circuits requiring level shifting or buffering
• Microprocessor system address/data latching

Procurement Notes

Verify the specific suffix 'DW' confirms the SOIC-20 package variant when sourcing. Confirm RoHS compliance status as manufacturing updates may affect environmental declarations. Ensure the intended application voltage aligns with the specified 4.5V to 5.5V range to maintain signal integrity and prevent device damage during operation.

Selection Notes

Select this component when an octal latch with moderate drive strength is required for 5V logic systems. Consider the SOIC-20 footprint for PCB layout constraints. Evaluate thermal performance if multiple units are placed closely together, as the standard industrial temperature range applies. Compare against similar Power Logic devices if higher current drive or different packaging options are needed.

Part Context

This part belongs to Texas Instruments' Power Logic family, which combines standard logic functions with enhanced output capabilities. The TPIC6273 series is engineered for applications requiring reliable data retention and noise immunity in digital environments. It serves as a fundamental building block for sequential logic circuits in consumer and industrial electronics.

Replacement Considerations

Direct substitutes include the TPIC6273DWRG4 and TPIC6273DW.A. Verify pin compatibility and electrical specifications before swapping. Alternative families like SN74LS273 offer similar logic but lack the specific Power Logic output characteristics.
